SHOE-LAST.

Specification of Letters Patent.

Patented July 18, 1916.

Application filed June 26, 1915. Serial No. 36,543.

To allwhom it may concern:

Be it known that I, PATRICK H. HIOKMAN', a citizen of the United States,residing at Irvington, in the county of Essex and State of New Jersey,have invented new and useful Improvements in Shoe-Lasts, of which thefollowing is a specification.

This invention relates to shoe lasts.

One object is to provide a shoe last embodying a toe and heel portionswingingly connected together with means cooperating with the swingingconnection to hold the toe and heel portions yieldingly at theiropposite limits of movement.

Another object resides in the provision of a. shoe last embodying a toeand a heel portion hingedly connected together and having means confinedin one of the portions which coacts with thehinged connection to holdthe toe and heel portions yieldingly in contracted or extendedpositions.

A still further object resides in the provision of a shoe last involvingtoe and heel portions hingedly connected together, in combination with aholding means constantly under tension for coaction with the hingedconnection between said portions, so as to hold the portions in theircontracted and extended positions.

WVith the above and other objects in view the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawing, and pointed out in the claimhereto appended, it being understood that various changes in the form,proportion, size and minor details of construction, within the scope ofthe claim, may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

In the drawing :-Figure 1 is a 'view, partly in side elevation andpartly in longitudinal section, illustrating the last with the toeportion in extended position with relation to the heel portion. Fig. 2is a similar view illustrating the toe and heel portions in contractedrelation. Fig. 3 is an inverted plan View of the last with the parts inextended relation. Fig. 4 is a detail view of the connectingplate'between the toe and heel portions. Fig. 5 is a detail view of theholding member which coacts with the said plate to yieldingly hold thesections in extended Or contracted position.

Referring now more particularly to the accompanying drawing, thereference char acters 2 and .3 indicate the heel and toe portionsrespectively, whose inner ends abut and meet on a curved line 6, overwhich" curved line the toe and heel portions are adapted to swingrelatively to each other. The heel portion is provided with a socket 5,in which maybe fitted a sleeve 4, whereby the last may be secured upon asuitable sup-' 'a pair of curved slots'12, formed upon the same are asthe line of curvature 6 at the abutting portions of the toe and heelportions, and this slotted portion of the plate 10 is adapted to extendinto the recess 9 of the toe portion and slidably held therein by meansof pins 13 passed transversely through the toe portion 3 and throughsaid slot 12.

The plate 10 has a cam edge resulting in the formation of notches 1 kand 15 and an intervening shoulder 16. By virtue of the plate connection10 between the toe and heel portions, it is clear that these portionsmay swing relative to each other along the curved line 6. The swingingof the heel portion 2 to contracted position with relation to the toeportion 3 is limited by virtue of the coacting shoulders 7 and 7 of thetoe and heel portions respectively. The swinging movement of these partsto extended position is limited by engagement with the lower face of theheel portion with the shoulders 7 at the rear of the toe portion.

I provide means to coact with the cam edge of the plate 10 to yieldinglyhold the toe and .heel portions at their limits of swinging movementrelative to each other.

One form of means for this purpose may consist of an arm 17 pivoted at18 in the recess 9 of the toe portion 3 and coacting with which is aspring 19 disposed in a recess 20 communicating with the recess 9 andbearing against the arm 17 to force the latter normally toward the heelportion of the last. This arm 17 is provided with a projection 21adapted to ride over the aforesaid shoulder 16 of the cam edge of theplate 10v and engage interchangeably in the notches 14 and 15 of the camedge of the plate 10, so as to yieldingly hold the heel portion inextended and contracted positions with relation to the toe portion ofthe last. In other words, when the heel portion 2 is swung to itsextended position with relation to the toe portion, the projection 21 ofthe arm 17 will fit in the recess 14 of the plate 10, and by virtue ofthe expansion of the spring 19, the heel portion will be yieldingly heldin its extended position with relation to the toe portion. When the heelportion 2 is thrown to contracted position with relation to the toeportion 3, the pivoted arm 17 will be swung forwardly on its pivot 18 byvirtue of the upward movement of plate 10 with heel portion 2,

and when the heel portion 2 has presented its shoulder 7 to the shoulder7 of the toe portion, the notch 15 in the plate 10 will have beenpresented to the projection 21 of the arm 17, with the result that thetension of the spring 19 will cause this projection 21 to bear with suchforce in the notch 15 as to yieldingly hold the heel portion in itscontracted position with relation to the toe portion.

What is claimed is A last including atoe section, a heel section, aplate fixed to the heel section and having sliding engagement only withthe toe section, said toe section being formed with a recess receivingsaid plate, the edge of the plate which projects within said recessbeing formed with spaced notches, a vertically extending latch memberpivotally supported within the recess of the toe section, said latchmember being formed with a projection adapted to enter the notches ofthe plate, whereby to hold the sections at the limit of their movementin either direction and a spring contacting with the latch member tomaintain the same in contact with the notched edge of the plate.

In testimony whereof I affix my signature in the presence of twowitnesses.
